Bootcamp booting clobbered by Yosemite upgrade

I've enjoyed being able to boot into OSX Mavericks or Windows 8.1 for the past year on my MBP (mid 2012, single 500GB SSD) but I recently performed the Yosemite upgrade. The resulting OSX installation appears to work fine but when I hold down the Option key after the chime the option to boot from Bootcamp Windows is missing. Worse, when I set "Startup Disk" to Bootcamp Windows the result fails.

@Loner T usually requests the following Terminal results so here they are:

I would appreciate help getting Bootcamp booting again.

attached is the log. I first cleared the log, then reconnected the USB HDD to log after that. At the end I see some "failed" items.

No attachments allowed I guess. Pasted below. Sorry. It's verbose.

The cloning process duplicated the UUIDs. Can you disconnect the SATA cable and only the USB? This will allow

1. Reverting the CS on the USB.

2. Randomizing the UUIDs on the jhfs+ exposed on the USB, using Gdisk.

3. Connect the SATA and test coexistence.

I removed the SSD and booted from the external USB HDD. Went fine. Results of reversion:

I then powered down, then booted to HDD to test it. I held the Option key down. I noted that two drives were shown (both external according to the icon): Macintosh HD and Recovery. So I assume disabling CS reveals the Recovery volume. I then changed the UUID using GDISK as you taught me earlier in this thread. That worked. Shut down, then booted again to make sure all was still okay with just the HDD connected. Worked.

After shutting down again I installed the SSD and booted with both drives connected (Option key held down). Three drives appeared: the SSD "Macintosh HD", the HDD "Macintosh HD", and the HDD Recovery. I chose the HDD "Macintosh HD" because prior to disabling CS and changing the UUID the system would insist on booting from the SSD regardless of which drive I chose.

During boot there was more activity from the HDD but I still couldn't tell whether the system booted from the SSD or the HDD. It seemed to boot fairly quickly, which makes me think it was the SSD. Below are the results of the two commands you taught me earlier. In your original instructions you referred to something being highlighted but I saw nothing highlighted so I still don't know how to interpret the following results.

Can you run a SMC Reset and NVRAM Reset and then test booting from the HDD? Please also check the Console logs for any error messages.

This shows that the boot was from a CS volume. Test with the SMC and NVRam reset.

I really need to use the MBP for the next few days. Might either of these procedures render it unusable? If so, I'd prefer to wait until I'm finished in a few days.

No, neither procedure will render you Mac unusable. The internal SATA SSD content or the HDD content is not begin modified in anyway with these two procedures. You may want to look through the two links which explains the details of exactly what is being done in each.

Loner T has been incredibly patient and helpful. Apple should be paying him!

I had to put this recovery project on hold starting Oct 3rd and was unable to return to it until today. Early in the thread Loner T provided instructions for recreating the Bootcamp boot record but I was wary about performing that operation to my Mac without first making a valid clone of the SSD. I discovered in the process that Terabyte's Image for Linux can successfully create a clone or image of the entire Mac drive. But I then got bogged down trying to have both the clone (in a USB 3 dock) and the SSD online, and boot from either. (I wanted to first perform the boot record recovery on the clone instead of my original SSD.) That probably occupied the last couple pages of this thread.

Upon returning to the project tonight and trying to figure out where we had left off I decided to try an entirely different approach to solving the problem.

I bought and installed Winclone Basic. I used it to make an image of the Bootcamp partition (remember: it's been visible all this time; the upgrade to Yosemite just screwed up booting to it). Then I restored that image. Russell Scheil of Two Canoes Software had told me that Winclone would recreate the boot record as part of its restore process.

I'm happy to report that after rebooting and holding down the Option key my Bootcamp partition is once again accessible. It's baaack!

Thank you to Loner T and to Russell Scheil for your help.

Please ensure you continue a regular backup regimen. Glad to see it working. I will play with TBIL soon. It seems to be a nice tool.
